Additionally, as your robot is angled, the weight distribution to each wheel will change, also changing the resulting normal force on each wheel (which could also cause a change in direction).

However, if you're using a holonomic drivetrain (w/ 4 45 degree angled omniwheels) that doesn't have all the wheels in contact, it will autocorrect itself, putting you straight.
